You have less than 4 billions degrees of freedom but you try to create a matrix with more than 4 billions elements and because by default we use unsigned int in deal.II you get an overflow error and the code does weird thing. The easy fix is to recompile deal.II with -DDEAL_II_WITH_64BIT_INDICES=ON then instead of using unsigned int we use unsigned long long int in the library and you won't get any overflow problem.
